Experiment set CHEMISTRY 5: ELECTROCHEMISTRY 2

Description

Electrochemistry for upper secondary level

With the MEKRUPHY ELECTROCHEMISTRY 2 experiment set, there is finally the ability to conduct age-oriented student experiments in electrochemistry for the upper secondary school level. It takes up major topics from ELECTROCHEMISTRY 1, consistently developing them further in advanced experiments. Students start, for example, from the no-load voltage of galvanic cells, and proceed in interesting measurement series from the investigation of the standard potential to the study of concentration cells and the development of the Nernst equation. The astonishingly simple design makes it possible for them to establish the normal potential on their own. It not only takes the place of a completely assembled and relatively expensive hydrogen electrode, but also makes the corresponding chemical processes even more transparent and comprehensible.

Compact design

The practical, stable beaker stand made of powder-coated aluminium can hold four 25-ml beakers and two 50-ml beakers simultaneously. Its centre of gravity is so low that it cannot fall over. Four small rubber feet provide additional security.
